Crossing the International Date Line shifts calendar dates by a day
Pacific oceanic date boundaries adjust calendar days for global travellers
The International Date Line roughly follows the 180-degree meridian through the Pacific Ocean, acting as the global boundary between calendar days. Travellers crossing the line westward advance their calendar date by one day, while those crossing eastward subtract a full twenty-four hours from their voyage log.
